BUBNER FOR LIQUID COMBUSTIBLES.

Application filed June 23, 1921'. Serial No. 479399.

To all whom it may conem: u

Be it known that I, CHARLES LINK, en ineer, citizen of the FrenchRepublic, residin at Paris, in the Department of the Seine, France, haveinvented certain new and useful Improvements in Burners for LiquidCombustibles, of which the following is a specification.

The invention'has for its subject improvewhich permit of obtainingcomplete combustion without smoke of liquid combustibles of any densityand the inve tion relates more particularly to liquid com ustibles ofthe less fluid type such as mazout, naphtha, heavy oils, etc.

In its simplest form, the-burner essentially comprses a casing dividedin two superposed compartments one of which receives the liquidcombustible, the other being in communication with a suitable source offluid under pressure. The two compartments which are of rectangularcross section are very shallow and lead to a` nozzle or dis- .tributionmouth-piece disposed in a horizontal plane insuch a manner as to directinto the furnace a sheet of atomzed combustible which escapes from theburner.

In the accompanying drawing:

Figure 1 is a transverse section of a burner constructed according tothe-invention. A F igure 2 is an end view of the same burner, inelevation. p

F igure 3 is a plan vewof the cleaning tool of the burner. P i

Figure 4 shows the handle of the cleamng tool'shewn on Fig. 3.

Figure 5 is a cross section through the nozzle-line A-B, Fig. 1.

l`he burner, Figures 1 and 2 is mounted on two rods 16-16 fixed to theironi: wall of a furnace. These rods pass. through two brackets 17-17cast integrally with the bottom part 18 of the burner; the two rods actas slides on which the burner can be moved back when cleaning isnecessary. The con nections of the burner with the mains is made byflexible pi es and proper kuce joints. If desired, te two rods could bemade of tubing, through which the air necessary to thecombustion couldpass.

On the furnace wall are' provided two grooves 19--19 also, in` which canbe slid a plate, in order to close the opemng n the ments in burners forliquid combustibles wall and protect it, when the burner is set back;cold air is then prevented from entern the furnace and in uring itsparts.

V he front wall is provided with a kind of cup 20 also cast integrallywith it, and in ths petroleum is poured for starting the burner.

The compartments of the burner comprise, atop (part 21, a bottom art 18, and an interme ate plate 22 on w ich falls the liquidcombustiblecoming from the tubing 23.

Towards its end the plate 22 is provided 'with a transverse groove 24 inwhich the liquid fuel pouredon .it flows, distributing itself uallyacross the width of the plate efore owing over the extreme end which hasthe shape ofa weir. 4

The groove 24: can be placed if required ust underneath the tubin oropening 23, it would act there as a kin of reservoir.

A somewhat large opening is provided on the top part 21 of the burner,it is closed by a cover or cap 26 which is lifted for inspecton orcleaning; said cap is itself provded with a smaller opening ,which canbe closed by a cover 27 linked to a chain. When the burner is acting,cover 27. is removed and part of the air required for combustionpasesjthrough the opening, as shewn by the arrow, said air flowng fromabove to the point where the liquid fuel is pulverized. i The top partof the nozzle as well as the tongue of plate 22 are corrugated as shewnFgure 5; these ridges produce undulations in the jet, increasing .thesurface of contact between the combustible liquid and the hot airsupplied to the furnace, and so contributing to the total combustion.

In the bottom part 18 are provided two openmgs 28-29 to be connected, 28with the pipe through .which flows the fluid re-' qured for thepulverization, and 29 with a The`vertical extent, as well as 'the width,of the passage 30 for the pulverizing fluid is regulated by acylindrical piece 31 on the circumference ofwhich two flat parts 32- 32have been cut, one narrower than the other. Regulation is obtained byturning round said piece 31 of the required amount. When in its rightplace piece 31 is fixedwith a set screw not shewn.

The cleaning of the opening 30 is made with a scraper 33, F igures 1 and3, fixed on a handle 34 on the remote end of which is a screw 35. ll`hishandle can slide in a sleeve 36 screwed in the bottom of the burner aidsleeve, when the burner is working, being closed by a plug 37, whichplug can be' screwed on the sleeve and on the screw 35 4 of the handle34:; the bottom part of the burner is on account of this, proof againstleakage, and besides the scraper is Secured in the sleeve.

For cleaning the plug 37 is removed and -one screws the handle 38through'39 to the screw 35 of the scraper 33. A reciprocatory motion isthen imparted to the cleaningtool,

nel in which fiows the liquid. In this 'case it will be necessary ofcourse 'to disconnect' the piping which then must be provided withproper quick setting joints. If the cover is 'made to oscillatehorizontally 'on a pivot, the changes-in shape of the piping may besmall and disconnection avoided. If there is no pressure inside, thecover, of course, may be simply put on; in this case closed connectionbetween the burner and 'the feeding piping is unnecessary, and the,liquid fuel may then descend through an opening on which a funnel couldbe placed.

When the burners are divided in several parts which can be eitherconnected or .dis connected through an automatic regulator of feed, itis necessary to have as many separate pipes or funnels that there areseparate burners, but in order to prevent the tendency of the liquidfuel, in this case, to

distribute itself all over, it is' good to provide some kindpf guideplates from which the liquid falls in drops.

l. In a bumerfor' liquiduel the combination of upper and lower chambersseparated by amedially arranged fuel' carrying plate, opposite openingsformed'in the walls of said chambers and extending along the margin ofsaid. separa'ting plate, means for maintaining a flow of-- gas under.``ressure through one of said chambers and rom the said opening in thewall thereof, means `for maintaining a flow of flame-nourishingairthrough the V other chamber and from the said opening in the wallthereof, and means for maintaining a stream of fluid fuel over saidplate and from the margins thereof between the openings in the chambers.

2. In a fluid fuel burner a transversely extending plate adapted tosustain a stream of fluid fuel and to allowthe fuel to escape by gravityover its edge, a nozzle wall arranged beneath and 'opposite the edge ofsaid; plate and forming therewith a nozzle, such nozzle forming theorifice of a Conduit for compressed gas, and a movable member arrangedadjacent the orifice formed by and. between the said nozzle wall andthe' edge of saidplate andbyv movement 'efl ecting variation in size ofsuch orifice.

3. In a fluid fuel burner the combination with a transversely extendingplate adapted to sustain'a stream of fluid fuel and to allow the fuel toescape by gravity over`its edge, a nozzle wall arranged' beneath andopposite the edge ofsaid plateand formng' therewith a noz zle, means forcausing a stream of compressed gas to' flow through said nozzle, anda'scraper borne by the :structure and adapted to be advanced throughsaid nozzle and retracted again to inactive position;
